The game of Battlefields is pretty straightforward. Drive your tank around the
battlefield and shoot everything! The more stuff you shoot, the more you earn;
and the more you earn, the more upgrades you can buy at the end of the level.
But as usual, the things you're trying to shoot are also trying to shoot you!
Luckily, you can also shoot down the bullets that your enemies throw your way.
If you're fast enough.
